Register on the electoral roll

Being registered to vote at your current address is one of the simplest, highest-impact steps — it helps lenders verify your identity and address, and its absence is a common, easily fixed reason for a lower score.

Pay everything on time

Payment history is one of the most heavily weighted factors in credit scoring. Setting up direct debits for at least the minimum payment on every credit commitment removes the risk of an accidental missed payment doing lasting damage to your file.

Keep credit utilisation low

Using a high proportion of your available credit — particularly on credit cards — can count against you, even if you pay in full every month. Keeping utilisation comfortably below around 30% of your available limit, where possible, tends to look more favourable than regularly maxing out cards.

Avoid unnecessary credit applications

Each credit application generally triggers a "hard search," visible to other lenders, and several in a short period can look like financial distress. Use eligibility checkers (which use a "soft search," invisible to other lenders) before formally applying, and space out genuine applications where possible.

Build a track record if you have little credit history

If you have little or no credit history — common for younger people or recent arrivals to the UK — a low-limit credit card used lightly and paid off in full each month can help build a positive track record over time, more effectively than avoiding credit altogether.

Correct errors on your file

Occasionally, credit files contain genuine errors — an account that isn't yours, an incorrect address, or a payment wrongly marked as missed. You can dispute inaccurate information directly with the credit reference agency, which must investigate and correct genuine errors.

Key takeaways

  • Electoral roll registration and on-time payments are foundational, high-impact factors.
  • Keep credit utilisation low, even if you always pay your balance in full.
  • Use soft-search eligibility checkers before applying to avoid unnecessary hard searches.
  • Dispute genuine errors on your credit file directly with the relevant agency.
